BACKGROUND

1. Field of the Disclosure

This disclosure relates to extracting data displayed on a touch screenby performing a touch operation on the touch screen surface using aninstruction object.

2. Description of the Related Art

Mobile devices, such as smart phones, are available for displaying dataon a screen. The displayed data may include pictures, text, videos, orweb pages. The mobile devices may include a touch screen, which may beconfigured to accept user inputs in the form of a touch operation. Thetouch operation may correspond to the user contacting the surface of thetouch screen with an instruction object, such as a finger or stylus. Thedata displayed at the touch screen coordinates where the user performsthe touch operation may correspond to data on which the user desiresfurther processing be performed.

Due to size considerations of many mobile devices, the touch screen maydisplay data in such a way that accurately selecting particular databecomes difficult. For example, a user performing a touch operation toselect a particular desired word within a displayed text paragraph mayresult in a word adjacent to the desired word being erroneouslyselected. This results in additional touch operations or unnecessaryprocessing being performed, which is inconvenient to the user.

DETAILED DESCRIPTION

Referring now to the drawings, wherein like reference numerals designateidentical or corresponding parts throughout the several views.

FIG. 1 illustrates a schematic block diagram of an exemplary mobilephone terminal device 100. As shown in FIG. 1, the mobile phone terminaldevice 100 may include an antenna 101 and a wireless communicationprocessing section 102. The wireless communication processing section102 may communicate wirelessly via radio signals, or the like, withother mobile devices via, e.g., a base station. Further, a data signal,such as a voice transmission from another user, may be received byantenna 101 and sent to the wireless communication processing section102 for further processing. In the case of an incoming voicetransmission, the voice data signal may be sent from the wirelesscommunication processing section 102 to a voice processing section 103.Incoming voice data received by the voice processing section 103 via thewireless communication processing section 102 may be output as sound viaa speaker 104.

Conversely, an outgoing voice signal may be supplied by a user to thevoice processing section 103 via a microphone 105. The voice signalreceived via microphone 105 and processed by the voice processingsection 103 may be sent to wireless communication processing section 102for transmission by the antenna 101.

A second antenna 106 may be supplied for use with a short distancewireless communication processing section 107. The short distancewireless communication processing section 107 may communicate wirelesslywith other devices over a network, such as the Internet, a local areanetwork (LAN), or a wide area network (WAN). The second antenna 106 may,e.g., by a Wi-Fi transceiver.

A sensor section 108 may be provided for the mobile phone terminaldevice 100. The sensor section 108 may be a motion sensor that detects amotion of an object in the proximity of the mobile phone terminal device100. The motion may correspond to a user moving an instruction object,such as a finger or stylus, in the proximity of the mobile phoneterminal device 100 for the purpose of selecting data displayed ondisplay 120.

The mobile phone terminal device 100 may include display 120. Thedisplay 120 may be, e.g., a liquid crystal display (LCD) panel, anorganic electroluminescent (OLED) display panel, a plasma display panel,or the like. The display 120 may, e.g., display text, an image, a webpage, a video, or the like. For example, when the mobile phone terminaldevice 100 connects with the Internet, the display 120 may display textand/or image data which is transmitted from a web server in Hyper TextMarkup Language (HTML) format and displayed via a web browser. Thedisplay 120 may additionally display data stored in a memory 150.

A touch panel section 130 can detect a touch operation on the surface ofthe display 120. For example the touch panel 130 can detect a touchoperation performed by an instruction object, such as a finger orstylus. Touch operations may correspond to user inputs, such as aselection of an icon or a character string displayed on the display 120.The touch panel section 130 may be an electrostatic capacitance typedevice, a resistive type touch panel device, or other such type devicesfor detecting a touch on a display panel.

The touch panel section 130 may perform processing related to touchoperation classification. For example, the touch panel section 130 mayassign a predetermined function to be performed when a “tap” touchoperation is detected. Similarly, the touch panel section may analyze atouch operation in which the instruction object makes continuous contactwith the display 120 while moving the instruction object around thedisplay 120 (e.g., a “swipe” operation). The touch panel section 130 mayoutput a signal based on a classification of the touch operationperformed. The signal may, e.g., include information indicating thetouch operation classification, the location on the display 120 wherethe touch operation was performed, and the operation to be performedbased on the touch operation.

Data which is detected and processed by the touch panel 130 can betransmitted to a controller 110. The controller 110 may include one ormore processor units and can control each element of the mobile phoneterminal device 100 based on data detected by the touch panel 130, or byinputs received from operation key 140. The operation key 140 mayreceive inputs, e.g., from external control buttons included with themobile phone terminal device 100. The external control buttons may,e.g., control the volume, the power, or a hold operation for the mobilephone terminal device 100.

The controller 110 may execute instructions stored in the memory 150. Tothis end, the memory 150 may be a non-transitory computer readablemedium having instructions stored therein for controlling the mobilephone terminal device 100. Further, the controller 110 may include oneor more processors for executing the instructions stored on the memory150. The memory 150 may additionally store classification tables andcharacter string tables, which are described in detail in laterparagraphs with respect to the non-limiting examples illustrated in FIG.4. In one aspect, the controller 110 may utilize the classificationtables and/or the character string tables stored in the memory 150 inexecuting instructions for the mobile phone terminal device 100.However, the processing features of the controller 110 are not limitedto using such tables, and other methods of performing these features maybe utilized.

The mobile phone terminal device 100 can include a control line CL and adata line DL as internal bus lines for communication. The control lineCL can be used to transmit control data from the controller 110. Thedata line DL may be used for the transmission of voice data, displaydata, or the like, throughout the various elements of the mobile phoneterminal device 100.

FIG. 2 illustrates a non-limiting example of an algorithmic flowchartfor extracting and analyzing data selected from a mobile device touchpanel display. At step S11, a user encloses a data element displayed onthe display 120 using an instruction object, such as a finger or astylus. For example, the user may perform a circular type motion on thedisplay such that a character string is enclosed within the circle. Itshould be appreciated that the touch operation of enclosing a dataelement on the display 120 is not limited to circular shapes. Such atouch operation may take the form of any “enclosed shape,” which aredefined hereinafter as any shape having continuous/connecting sides(e.g., a circle, an oval, a polygon, or any free-form shape withunbroken sides enclosing an area within).

FIG. 5 provides a non-limiting example of a touch operation that may beperformed at step 11 of FIG. 2. Referring to FIG. 5, a user may encirclespecific text from the plurality of text data displayed on display 121,wherein the user desires the controller 110 perform further processingon the encircled text. As an exemplary touch operation, the user mayenclose text which the user wishes to extract for further processing bymaintaining contact on the display 121 surface with an instructionobject while moving the instruction object in a circular motion, asillustrated by circle C1.

Referring back to FIG. 2, the controller 110 extracts all the characterstrings enclosed by the user operation performed at step S11 based on aninput from the touch panel 130 (step S12). The controller 110 mayextract a character string corresponding to a displayed character stringin which all or part of the displayed string is enclosed within thetouch operation performed at step S11. The extracted character string isthen processed by an algorithm for extracting selected candidatecharacter strings (step S20) to identify one or more candidate characterstrings.

At step S21, the controller 110 divides the circle drawn by the user atstep S11 into a plurality of portions using the starting point andending point of the touch operation as reference. See, e.g., regionsA1-A6 increasing sequentially from the starting point to the endingpoint of the touch operation illustrated in FIG. 3. The controller 110classifies the character strings displayed in the respected dividedportions using a predetermined classification method with which toanalyze the candidate character strings. Each classification outcome forthe classified candidate character strings may be assigned an associatedclassification priority value. Each divided portion of the circle mayalso be assigned an associated position priority value.

As an exemplary method of prioritizing the classified candidatecharacter strings, the controller 110 multiplies the classificationpriority value by the position priority to obtain a value whichdetermines the order in which the candidate character string isdisplayed. At step S22, the candidate character strings are sorted basedon the determined priority order value.

At step S13, the display 120 displays the candidate character stringsaccording to the determined priority order. For example, the display 120may display the candidate character strings from the one that has thelargest determined value to the one that has the smallest determinedvalue. At step S14, a user may select any one of the character stringsdisplayed in priority order on display 120. Once a character string isselected at step S14, a processing method associated with the associatedcharacter string may then be executed. At step S15, the controller 110executes the associated processing method of the selected characterstring. For example, the selected character string may be a web link.Thus, when the web link is selected using the method of FIG. 2, thecontroller 110 may perform at step S15 an operation of downloading a webpage corresponding to the selected web link.

FIG. 3 illustrates an exemplary display transition for mobile phoneterminal device 100 according to the method of FIG. 2. Referring to FIG.3, the user touches the surface of the display 120 with an instructionobject, illustrated in this example by finger f, and traces circle C onthe display 120. The controller 110 divides the area enclosed by thecircle C based on a start point and an end point. The division resultsin forming six regions A1-A6 within the circle C. It should beappreciated that while six regions are shown in FIG. 3 for illustrationpurposes, the controller 110 may divide the enclosed area by any numberof regions.

The controller 110 extracts each character string or word which overlapsthe location of each respective region A1-A6. In the case where multiplecharacter strings are contained within a divided region of circle C, theentirety of the divided region is analyzed, and each individualcharacter string within the region boundary is extracted. If only aportion of a character string is within the boundary of a dividedregion, the controller 110 may be configured to extract the entirecharacter string corresponding to the overlapping portion. Further, thecontroller 110 may associate a character string overlapping multipledivided regions to each overlapped region, or may identify a singleregion for association.

As discussed with respect to FIG. 2, each extracted candidate characterstring is sorted according to a predetermined characterization andpriority method. After sorting the extracted candidate characterstrings, the prioritized character string list may then be displayed toa user on the display 120. Display area 121 a of FIG. 3 is an example ofsorted character strings extracted from regions A1-A6.

Each extracted character string from regions A1-A6 may have apredetermined function associated with the character string. Forexample, when the extracted character string includes one or more words,processing functions associated with the extracted text may includecopying the text and/or searching the extracted text using a searchengine application. Display areas 121 b and 121 c of FIG. 3 illustrateexemplary processing functions which may be associated with an extractedcharacter string and displayed to a user for selection. These displayareas may be output on the display 120 when the user selects anextracted and prioritized character string, e.g., from the display area121 a. In the example of display area 121 b, a character stringextracted in region A1 may have associated functions of copying thetext, searching the text in a site A, or searching the text in a site B.In the example of display area 121 c, the extracted character stringfrom region A3 may be a web uniform resource locator (URL) address,wherein the extracted URL has associated functions of activating a webbrowser, copying the URL, or activating an electronic mail application.

The associated processing functions discussed above for display areas121 b and 121 c may be executed by the controller 110 when a userselects a desired function from a list of associated functions, such asthat in display area 121 c. Alternatively, an associated function may beexecuted immediately upon selection of an extracted and prioritizedcharacter string (i.e., the processing associated with displayingdisplay areas 121 b and 121 c may be omitted).

FIG. 4 illustrates a non-limiting example of processing related to anexemplary classification table 400 and an exemplary characterizationstring table 402. As shown in FIG. 4, the classification table 400includes six exemplary classification IDs represented as ID 1 through ID6.

ID 1 represents a classification of an extracted candidate characterstring as a web address. The classification may be performed, e.g., bydetermining the extracted candidate character string begins with“http://,” “https://,” “ftp://,” etc. In the example of FIG. 4, ID 1 hasthree associated processing functions, which include activating a webbrowser, copying the web link, or activating an electronic mailapplication. Classification table 400 assigns a classification priorityvalue of 50 to the ID 1 classification.

ID 2 represents a classification of a candidate character stringconsisting of the word “mailto” or “@.” This classification may, e.g.,represent an e-mail address. In the example of FIG. 4, ID 2 has oneassociated processing function of activating an electronic mailapplication. Classification table 400 assigns a classification priorityvalue of 25 to the ID 2 classification.

ID 3 represents a classification of a candidate character stringconsisting of a sentence wherein the first word of the sentence iscapitalized and the sentence ends in a period. In the example of FIG. 4,ID 3 has two associated processing functions, which include copying theextracted sentence or performing a re-extraction. Classification table400 assigns a classification priority value of 30 to the ID 3classification.

ID 4 represents a classification of a candidate character stringconsisting of consecutive words whose first letters are capitalized(e.g., Los Angeles). In the example of FIG. 4, ID 4 has two associatedprocessing methods, which include copying the consecutive words orsearching the words on a search engine included in a site A.Classification table 400 assigns a classification priority value of 40to the ID 4 classification.

ID 5 represents a classification of a candidate character string whichbegins with a preposition (e.g., in, to, at, etc.). ID 5 may alsorepresent a classification of a character string enclosed by a period ora comma. In the example of FIG. 4, ID 5 has three associated processingmethods which include copying the character string, searching thecharacter string in a search engine on a site A, or searching thecharacter string in a search engine on a site B. Classification table400 assigns a classification priority value of 30 to the ID 5classification.

ID 6 represents a classification of a candidate character stringconsisting of a word or words which are close to the center of the areaenclosed by the user's touch operation. In the example of FIG. 4, ID 6has one associated processing method which includes copying the word orwords. Classification table 400 assigns a classification priority valueof 20 to the ID 6 classification.

The character string table 402 of FIG. 4 includes a position prioritynumber for each of the six regions A1-A6. Referring back to the exampleof FIG. 3, the regions are determined by analyzing a start point and anend point of a user's touch operation. In FIG. 3, a user performs atouch operation corresponding to drawing a circle C with finger f. Thestart point of circle C corresponds to region A1, and the regionsincrease sequentially to the circle's end point, which is represented byregion A6. Referring back to FIG. 4, the controller 110 determines theregion associated with an extracted and classified character string, andmultiplies the value of classification priority acquired from theclassification table 400 with the value of the position priorityacquired in the character string table 402. The result of themultiplication is shown in table 404.

As an example of the above-described classification and positionpriority value multiplication, when a candidate character stringclassified as ID 1 exists in a location corresponding to region A3, thevalue of 50 is assigned as a classification priority and a positionpriority value of 20 is assigned for region A3. These priority valuesare respectively assigned based on the information in the classificationtable 400 and the character string table 402. The classificationpriority value and the position priority value are then multiplied,resulting in a value of 1,000.

After determining the multiplication results for each divided region,the resultant values are sorted sequentially as shown in table 406. Inthe example of FIG. 4, the regions are sorted from highest to lowest.However, other sorting methods may be used. After sorting the calculatedvalues, controller 110 causes the display 120 to display the sortedcandidate character strings according to the sorted order of table 406.When displaying the sorted values, the controller 110 may cause thedisplay 120 to display all or a subset of the sorted values, whereinhidden sorted values may be viewed by performing a scroll operation.Further, the display 120 may display only the sorted values that exceeda predetermined threshold.

It should be appreciated that the classification table 400 and thecharacter string table 402 shown in FIG. 4 are merely illustrativeexamples and these tables are not limiting for the purposes of thecontroller 110 performing the above-described operations. Numerouscombinations of classification IDs, classification types, processingmethods, classification priority numbers, position priority numbers,etc., may be used in the classification and character string tables. Forexample, the priority values may be updated by the controller 110according to a user's preferences or a user's behavioralcharacteristics. In this case, when a user frequently selects characterstrings of a particular classification, the classification priorityvalue for that classification may be increased such that the associatedcharacter string is displayed prominently by default. The controller 110may also adjust the values in the FIG. 4 tables according to inputsreceived by a user. Further, the data used in the classification andposition priority methods of the controller 110 are not limited to theuse of tables, and other classification and priority methods may beutilized.

FIG. 5 illustrates an exemplary touch operation according to the methodof FIG. 2. FIG. 5 includes a mobile phone terminal device 100 with adisplay 120. The display 120 displays text to a user, wherein the usermay perform a touch operation to select specific text using aninstruction object, such as a finger or stylus. As shown in FIG. 5, theuser may perform a touch operation corresponding to tracing a circlewith the user's finger on the display 120 surface, as represented bycircle C1. Following the detection of the user's touch operation by thetouch panel section 130, the controller 110 extracts the characterstrings enclosed by the circle C1, e.g., using the method of FIG. 2. Thecontroller 110 then obtains candidate character strings which areclassified and prioritized using a predetermined method, such as themethod discussed above with reference to FIG. 4.

A character string may be output to the display 120 following theclassification and prioritization processing. Referring to FIG. 6, adisplay area 121 x may be output to the display 120 based on theclassification and prioritization result. Display area 121 x includesthe characterized and prioritized candidate character strings that wereenclosed by the circle C1 in FIG. 5. The example of FIG. 6 includesseven candidate character strings displayed in display area 121 x. Inthis example, the candidate character string with the highest priorityvalue based on, e.g., the process of FIG. 4, is placed at the top of thedisplay area 121 x, and so on.

When displaying the display area 121 x on the display 120, thecontroller 110 may control the display such that the background text onthe display 120 is lower in luminescence, thereby highlighting the listshown in display area 121 x via increased contrast. Further, thecontroller 110 may output the display area 121 x on the display 120 inany position within the display 120 viewable area. The example of FIG. 6shows the display area 121 x being displayed in a central region of thedisplay 120.

Following the display of the display area 121 x, a user may select oneof the displayed candidate character strings using another touchoperation (e.g., by tapping one of the character strings listed in thedisplay area 121 x). Referring to FIG. 7, the user selects the highestprioritized candidate character string, which in this case correspondsto a web address. Following the selection of the web address from thedisplay area 121 x, the controller 110 may output a display area 121 y,which includes the functions associated with the selected candidatecharacter string (i.e., the processing methods listed in theclassification table 400 of FIG. 4).

Turning to FIG. 7, the candidate character string in this case isclassified as ID 1 according to the classification table 400 of FIG. 4.According to the classification table 400, the classification of ID 1includes three associated processing methods: launching a web browser,copying the web address, and copying the web address and launching anelectronic mail application. Therefore, following the selection of theweb address character string from the display area 121 x, the controller110 outputs the three associated processing functions as a list indisplay area 121 y. After displaying the display area 121 y, the usermay perform another touch operation on the display 120 to select one ofthe three associated processing functions. Following the selection ofone of the processing functions, the controller 110 controls the mobilephone terminal device 100 to perform the selected processing function.

In another aspect of the present disclosure, character strings may beextracted using hypertext markup language (HTML). Referring to FIG. 8, auser may perform a touch operation with an instruction object, such as afinger or stylus, on the display 120. Display 120 displays textinformation to a user. The touch operation may correspond to a circle,such as circle C1, traced by the user on the display 120. Following thetouch operation, the controller 110 may extract the HTML source codecorresponding to the character strings enclosed within the circle C1.The controller 110 may then analyze the HTML code to determine theselected candidate character strings from within the HTML code. In thesyntax of HTML, a paragraph is shown with a <p> tag. That is, the rangeof text bracketed by two <p> tags comprises one paragraph, asillustrated in FIG. 8. The controller 110 extracts the range ofcharacters bracketed by the <p> tags as a candidate character string ofone unit. For example, the controller 110 may determine that a word orportion of a word which is enclosed by the circle C1 shown at the upperright of FIG. 8 was extracted. As shown in the lower right portion ofFIG. 8, the controller 110 determines that a paragraph tag is used andthe paragraph to which each selected word belongs is evaluated and thecharacter string extracted.

The controller 110 may also extract a candidate character string usingtags other than a paragraph tag. Moreover, the controller may extract acandidate character string using languages other than HTML.

Obviously, numerous modifications and variations of the presentinvention are possible in light of the above teachings. It is thereforeto be understood that within the scope of the appended claims, theinvention may be practiced otherwise than as specifically describedherein. For example, the display 120 shown in FIGS. 5-7 may beconfigured differently than those illustrated in the figures. Further,the values of the tables shown in FIG. 4 are merely examples and thedata contained within these tables may be different than that shown inFIG. 4. Moreover, sorting methods other than those illustrated anddiscussed with reference to FIG. 4 may be used to sort candidatecharacter strings. Additionally, devices other than the mobile phoneterminal device 100 shown in FIG. 1 may also be used to perform thefeatures discussed in present disclosure. For example, aspects of thepresent disclosure may be executed on a smart phone, a tablet, a generalpurpose computer, a laptop, an electronic reading device, or other suchdisplay terminals.
